UPDATE: Robert Downey Jr. has now revealed another image from the set, this time of the assembled chairs for the cast. We've added it below the original story.

Following Robert Downey Jr.'s debut image yesterday from the set of Avengers: Age of Ultron, it seems now The Hulk aka Mark Ruffalo is getting in on the picture taking. Just before releasing two images from the set of the highly-anticipated sequel, Ruffalo also tweeted the following:

Today was the first day of shooting "Age Of Ultron" when all of the Avengers we reassembled! Awesome sight! @Marvel

It might be too much to ask for a photo of the gang back together once again, but we can dream. You'll find the images that Ruffalo posted to his Instagram below.

Currently in production, the film is set to star Robert Downey Jr., Chris Hemsworth, Mark Ruffalo, Jeremy Renner, Chris Evans, Scarlett Johansson, Samuel L. Jackson, Thomas Kretschmann, Paul Bettany, Aaron Taylor Johnson, Elizabeth Olsen and James Spader. Written and directed by Joss Whedon, Avengers: Age of Ultron will hit theaters on May 1, 2015.​
